How to create an online store like "Burger King" and "McDonald's" on iOS and Android?

Question

Mobile development

Greetings to all comrades
How to create an Internet store like "Burger King" and "McDonald's" on iOS and Android?
- What are the stages of development (superficially)
- Do you need a Web version of the finished site?
I believe that when designing a mobile version, it is links from the domain of the official site that are used.
Help a complete loser to build a chain, how these stores are arranged.
I understand that they are currently being created mainly in AndroidStudio and XCode. I don't understand the specifics. Are images and other functionality loaded into .apk when they are created.
On YouTube, I did not find a single review in Russian that would at least somehow understand the hierarchy.
Any links or information would be greatly appreciated.

Answer 1

Do you need a Web version of the finished site?

We need a remote server with API. And in order to visualize the information for orders from a mobile phone, at least some kind of web form is required.

so I think when designing a mobile version, it is links from the domain of the official site that are used

If you are too lazy to write an API, you can use links, in this case you will need an adaptive version of the website for mobile phones and a custom web browser.

What are the stages of development

-Prototyping -Choice
of architecture -Creating
UI
-Writing logic
-Testing
-Publishing to the store
